ABSTRACT:
A method and apparatus are provided for effecting the periodic partial replacement of used lubricating oil with fresh lubricating oil in the oil-confining reservoir of an internal combustion engine. The apparatus utilizes a first container which holds fresh oil, a second container which holds used oil, and associated pumps which transfer fresh oil to the engine and remove used oil therefrom. Monitoring means record the extent of usage of the oil and dictate the operation of the pumps.
